【SpringBoot】---整合Shiro安全框架
【SpringBoot】---整合Shiro安全框架
一、什么是Shiro
●Apache Shiro
是一个Java 的安全(权限)框架。
●Shiro
可以非常容易的开发出足够好的应用,其不仅可以用在JavaSE环境,也可以用在JavaEE环境。
●Shiro
可以完成,认证,授权,加密,会话管理,Web集成,缓存等.
●下载地址: http://shiro.apache.org/
1、Shiro的功能
●Authentication: 身份认证、登录,验证用户是不是拥有相应的身份;
●Authorization:授权,即权限验证,验证某个已认证的用户是否拥有某个权限,即判断用户能否进行什么操作,如:验证某个用户是否拥有某个角色,或者细粒度的验证某个用户对某个资源是否具有某个权限!
●Session Manager: 会话管理,即用户登录后就是第-次会话,在没有退出之前,它的所有信息都在会话中;会话可以是普通的JavaSE环境,也可以是Web环境;
●Cryptography: 加密,保护数据的安全性,如密码加密存储到数据库中,而不是明文存储;
●Web Support: Web支持,可以非常容易的集成到Web环境;
●Caching: 缓存,比如用户登录后,其用户信息,拥有的角色、权限不必每次去查,这样可以提高效率
●Concurrency: Shiro支持多线程应用的并发验证,即,如在-个线程中开启另-一个线程,能把权限自动的传
播过去
●Testing:提供测试支持;
●RunAs:允许一个用户假装为另-一个用户(如果他们允许)的身份进行访问;
●Remember Me:记住我,这个是非常常见的功能,即一-次登录后, 下次再来的话不用登录了
2、Shiro架构(外部)
●subject: 应用代码直接交互的对象是Subject, 也就是说Shiro的对外API核心就是Subject, Subject代表了当前的用户,这个用户不-定是一个具体的人,与当前应用交互的任何东西都是Subject,如网络爬虫,机器人等,与Subject的所有交互都会委托给SecurityManager; Subject其实是一一个门面, SecurityManageer 才是
实际的执行者
●SecurityManager: 安全管理器,即所有与安全有关的操作都会与SercurityManager交互, 并且它管理着所有的Subject,可以看出它是Shiro的核心,它负责与Shiro的其他组件进行交互,它相当于SpringMVC的DispatcherServlet的角色
●Realm: Shiro从Realm获取安全数据 (如用户,角色,权限),就是说SecurityManager要验证用户身份,那么它需要从Realm获取相应的用户进行比较,来确定用户的身份是否合法;也需要从Realm得到用户相应的角色、权限,进行验证用户的操作是否能够进行,可以把Realm看DataSource
二、Hello-Shiro
1、创建一个空的maven项目
①依赖
<dependencies>

②Resources目录下添加log4j的配置文件
log4j.properties
log4j.rootLogger=INFO, stdout

log4j.logger.org.apache.shiro.cache.ehcache.EhCache=WARN
③Resources目录下添加shiro.ini文件
[users]
# user 'root' with password 'secret' and the 'admin' role
root = secret, admin
# user 'guest' with the password 'guest' and the 'guest' role
guest = guest, guest
# user 'presidentskroob' with password '12345' ("That's the same combination on

darkhelmet = ludicrousspeed, darklord, schwartz
# user 'lonestarr' with password 'vespa' and roles 'goodguy' and 'schwartz'
lonestarr = vespa, goodguy, schwartz
# -----------------------------------------------------------------------------
# Roles with assigned permissions
#
# Each line conforms to the format defined in the

*/
public class Quickstart {
private static final transient Logger log = LoggerFactory.getLogger(Quickstart.class);
public static void main(String[] args) {
// The easiest way to create a Shiro SecurityManager with configured
// realms, users, roles and permissions is to use the simple INI config.
// We'll do that by using a factory that can ingest a .ini file and
// return a SecurityManager instance:
// Use the shiro.ini file at the root of the classpath
// (file: and url: prefixes load from files and urls respectively):
//原本的方法
// Factory<SecurityManager> factory = new IniSecurityManagerFactory("classpath:shiro.ini");
// SecurityManager securityManager = factory.getInstance();
//新方法 shiro更新问题
DefaultSecurityManager securityManager = new DefaultSecurityManager();
IniRealm iniRealm = new IniRealm("classpath:shiro.ini");
securityManager.setRealm(iniRealm);
// for this simple example quickstart, make the SecurityManager
// accessible as a JVM singleton. Most applications wouldn't do this
// and instead rely on their container configuration or web.xml for

// we'll just do the bare minimum so you can continue to get a feel
// for things.

三、Spring Boot整合Shiro
1、环境搭建
①新建一个Spring Boot项目
pom.xml
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

</configuration>
</plugin>
</plugins>
</build>
</project>
②config配置
ShiroConfig
package com.darkerg.shiroboot.config;
import org.apache.shiro.spring.web.ShiroFilterFactoryBean;
import org.apache.shiro.web.mgt.DefaultWebSecurityManager;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
@Configuration
public class ShiroConfig {
//ShiroFilterFactoryBean
@Bean
public ShiroFilterFactoryBean getShiroFilterFactoryBean(@Qualifier("securityManager") DefaultWebSecurityManager defaultWebSecurityManager){
ShiroFilterFactoryBean bean = new ShiroFilterFactoryBean();
//设置安全管理器
bean.setSecurityManager(defaultWebSecurityManager);
return bean;
}
//DefaultWebSecurityManager
@Bean(name = "securityManager")
public DefaultWebSecurityManager defaultWebSecurityManager(@Qualifier("userRealm") UserRealm userRealm){
DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
//关联UserRealm
securityManager.setRealm(userRealm);
return securityManager;
}
//创建realm对象,需要自定义类
@Bean(name = "userRealm")
public UserRealm userRealm(){
return new UserRealm();
}
}
UserRealm
package com.darkerg.shiroboot.config;
import org.apache.shiro.authc.AuthenticationException;
import org.apache.shiro.authc.AuthenticationInfo;
import org.apache.shiro.authc.AuthenticationToken;
import org.apache.shiro.authz.AuthorizationInfo;
import org.apache.shiro.realm.AuthorizingRealm;
import org.apache.shiro.subject.PrincipalCollection;
//自定义的Realm
public class UserRealm extends AuthorizingRealm {
//授权
@Override
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
System.out.println("执行了授权");
return null;
}
//认证
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {
System.out.println("执行了认证");
return null;
}
}
③Controller层
MyController
package com.darkerg.shiroboot.controller;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
public class MyController {
@RequestMapping({"/","index"})
public String toIndex(Model model){
model.addAttribute("msg","hello,shiro");
return "index";
}
@RequestMapping("/user/add")
public String add(){
return "user/add";
}
@RequestMapping("/user/update")
public String update(){
return "user/update";
}
}
④前端页面
index.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<h1>首页</h1>
<p th:text="${msg}"></p>
<a th:href="@{/user/add}">add</a> | <a th:href="@{/user/update}">update</a>
</body>
</html>
add.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<h1>添加一个用户</h1>
</body>
</html>
update.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<h1>修改一个用户</h1>
</body>
</html>
2、实现登录拦截
①添加Shiro的内置过滤器
在Shiro配置类中修改下面的方法
@Bean
public ShiroFilterFactoryBean getShiroFilterFactoryBean(@Qualifier("securityManager") DefaultWebSecurityManager defaultWebSecurityManager){
ShiroFilterFactoryBean bean = new ShiroFilterFactoryBean();
//设置安全管理器
bean.setSecurityManager(defaultWebSecurityManager);
//添加shiro的内置过滤器
/**
* anon:无需认证就可以访问
* authc:必须认证了才能访问
* user:必须拥有 记住我 功能才能用
* perms;拥有对某个资源的权限才能访问
* role:拥有某个角色权限才能访问
*/
Map<String, String> filterMap = new LinkedHashMap<>();
filterMap.put("/user/add","authc");
filterMap.put("/user/update","authc");
//或者使用通配符
//filterMap.put("/user/*","authc")
bean.setFilterChainDefinitionMap(filterMap);
return bean;
}
此时我们访问添加和更新的页面,会报错,说明拦截成功了。
②编写一个登录的页面
实现拦截之后,跳转到登录页面。
login.html
<!DOCTYPE html>
<html lang="en" xmlns:th="https://www.thymeleaf.org">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<h1>登陆</h1>
<hr>
<p style="color: red" th:text="${msg}"></p>
<form th:action="@{/login}">
<p>用户名:<input type="text" name="username"></p>
<p>密码:<input type="password" name="password"></p>
<p><input type="submit"></p>
</form>
</body>
</html>
同时编写相应的控制器
@RequestMapping("/toLogin")
public String toLogin(){
return "login";
}
③在拦截方法下面加上登录url
此时就实现了登录拦截。
3、实现用户认证
①添加一个登录接口
@RequestMapping("/login")
public String login(String username,String password,Model model){
//获取当前用户
Subject subject = SecurityUtils.getSubject();
//封装用户的登录数据
UsernamePasswordToken token = new UsernamePasswordToken(username, password);
try {
subject.login(token);//执行登录的方法,如果没有异常说明就ok了
return "index";
} catch (UnknownAccountException e) {//用户名不存在
model.addAttribute("msg","用户名错误");
return "login";
} catch (IncorrectCredentialsException e){//密码不存在
model.addAttribute("msg","密码错误");
return "login";
}
}
此时重新发布项目,然后点击登录之后,会出现用户名不存在。因为我们还没有添加认证。
②在UserRealm自定义Realm中添加认证的细节
//认证
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {
System.out.println("执行了认证");
//用户名,密码 数据库中去取
String name = "root";
String password = "123456";
UsernamePasswordToken userToken = (UsernamePasswordToken) authenticationToken;
if (!userToken.getUsername().equals(name)){
return null;//抛出异常 UnkonwAccountException
}
//密码认证,shiro做
return new SimpleAuthenticationInfo("",password,"");
}
4、Shiro整合Mybatis
①添加依赖
<!--lombok-->
<dependency>
<groupId>org.projectlombok</groupId>
<artifactId>lombok</artifactId>
</dependency>
<!--mysql-->
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
</dependency>
<!--log4j-->
<dependency>
<groupId>log4j</groupId>
<artifactId>log4j</artifactId>
<version>1.2.17</version>
</dependency>
<!--druid数据源-->
<!-- https://mvnrepository.com/artifact/com.alibaba/druid -->
<dependency>
<groupId>com.alibaba</groupId>
<artifactId>druid</artifactId>
<version>1.2.8</version>
</dependency>
<!--MyBatis-->
<dependency>
<groupId>org.mybatis.spring.boot</groupId>
<artifactId>mybatis-spring-boot-starter</artifactId>
<version>2.2.0</version>
</dependency>
②新建一个shiro数据库
user表
③新建application.yaml
spring:
datasource:
username: root
password: root
url: jdbc:mysql://localhost:3306/shiro?useUnicode=true&characterEncoding=UTF-8&useJDBCCompliantTimezoneShift=true&useLegacyDatetimeCode=false&serverTimezone=UTC
driver-class-name: com.mysql.cj.jdbc.Driver
type: com.alibaba.druid.pool.DruidDataSource
#Spring Boot 默认是不注入这些属性值的,需要自己绑定
#druid 数据源专有配置
initialSize: 5
minIdle: 5
maxActive: 20
maxWait: 60000
timeBetweenEvictionRunsMillis: 60000
minEvictableIdleTimeMillis: 300000
validationQuery: SELECT 1 FROM DUAL
testWhileIdle: true
testOnBorrow: false
testOnReturn: false
poolPreparedStatements: true
#配置监控统计拦截的filters,stat:监控统计、log4j:日志记录、wall:防御sql注入
#如果允许时报错 java.lang.ClassNotFoundException: org.apache.log4j.Priority
#则导入 log4j 依赖即可,Maven 地址:https://mvnrepository.com/artifact/log4j/log4j
filters: stat,wall,log4j
maxPoolPreparedStatementPerConnectionSize: 20
useGlobalDataSourceStat: true
connectionProperties: druid.stat.mergeSql=true;druid.stat.slowSqlMillis=500
mybatis:
type-aliases-package: com.huang.pojo
mapper-locations: classpath:mybatis/mapper/*.xml
④application.properties配置一下
⑤pojo新建实体类User
package com.darkerg.shiroboot.pojo;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
@Data
@AllArgsConstructor
@NoArgsConstructor
public class User {
int id;
String name;
String pwd;
}
⑥mapper下新建UserMapper
package com.darkerg.shiroboot.mapper;
import com.darkerg.shiroboot.pojo.User;
import org.apache.ibatis.annotations.Mapper;
import org.apache.ibatis.annotations.Param;
import org.apache.ibatis.annotations.Select;
import org.springframework.stereotype.Repository;
@Repository
@Mapper
public interface UserMapper {
@Select("select * from user where name = #{name}")
public User queryUserByName(@Param("name") String name);
}
⑦Service层
UserService就不放了,重新写一下就行。
UserServiceImpl
package com.darkerg.shiroboot.service;
import com.darkerg.shiroboot.mapper.UserMapper;
import com.darkerg.shiroboot.pojo.User;
import org.springframework.beans.factory.annotation.Autowired;
public class UserServiceImpl implements UserService{
@Autowired
UserMapper userMapper;
@Override
public User queryUserByName(String name) {
return userMapper.queryUserByName(name);
}
}
⑧重写UserRealm---连接数据库版
package com.darkerg.shiroboot.config;
import com.darkerg.shiroboot.pojo.User;
import com.darkerg.shiroboot.service.UserServiceImpl;
import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authc.*;
import org.apache.shiro.authz.AuthorizationInfo;
import org.apache.shiro.realm.AuthorizingRealm;
import org.apache.shiro.subject.PrincipalCollection;
import org.apache.shiro.subject.Subject;
import org.springframework.beans.factory.annotation.Autowired;
//自定义的Realm
public class UserRealm extends AuthorizingRealm {
@Autowired
UserServiceImpl userService;
//授权
@Override
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
System.out.println("执行了授权");
return null;
}
//认证
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {
System.out.println("执行了认证");
UsernamePasswordToken userToken = (UsernamePasswordToken) authenticationToken;
//连接真实的数据库
User user = userService.queryUserByName(userToken.getUsername());
if (user == null){//没有这个人
return null;
}
//密码认证,shiro做
return new SimpleAuthenticationInfo("",user.getPwd(),"");
}
}
此时,重启项目,输入用户名密码即可登录了。
5、Shiro请求授权的实现
①在ShiroConfig的过滤器中添加授权功能测试
@Bean
public ShiroFilterFactoryBean getShiroFilterFactoryBean(@Qualifier("securityManager") DefaultWebSecurityManager defaultWebSecurityManager){
//....和上面的一样
//授权,未授权的情况下会跳转到未授权的页面。
filterMap.put("/user/add","perms[user:add]");
filterMap.put("/user/update","perms[user:update]");
}
此时登陆之后,再次点击add请求,会出现未授权的错误页面
除此之外,还可以通过Shiro定制未授权的请求。
bean.setUnauthorizedUrl();
②在UserRealm中添加授权功能
//授权
@Override
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
System.out.println("执行了授权");
SimpleAuthorizationInfo info = new SimpleAuthorizationInfo();
info.addStringPermission("user:add");
return info;
}
然后重新启动项目,发现可以进去add的请求了,但是现在的问题就是所有的用户都可以访问add请求。那么如何为特定的用户添加呢?
③为特定用户添加特定的权限
修改数据库,添加权限的字段,同时别忘了要在Pojo实体类中也添加相应的属性。
④授权如何获得认证的信息
在认证的时候添加,然后再授权的时候提取。
//授权
@Override
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
System.out.println("执行了授权");
SimpleAuthorizationInfo info = new SimpleAuthorizationInfo();
info.addStringPermission("user:add");
//拿到当前登录的这个对象
Subject subject = SecurityUtils.getSubject();
User currentUser =(User) subject.getPrincipal();//拿到User对象
//设置当前用户的权限
info.addStringPermission(currentUser.getPerms());
return info;
}
//认证
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {
System.out.println("执行了认证");
UsernamePasswordToken userToken = (UsernamePasswordToken) authenticationToken;
//连接真实的数据库
User user = userService.queryUserByName(userToken.getUsername());
if (user == null){//没有这个人
return null;
}
//密码认证,shiro做
//此处,把user放进去
return new SimpleAuthenticationInfo(user,user.getPwd(),"");
}
到目前位置,darkerg用户登录上去之后,只可以点击update了。
6、Shiro整合Thymeleaf
①添加Maven依赖
<!--Shiro-thymeleaf整合-->
<!-- https://mvnrepository.com/artifact/com.github.theborakompanioni/thymeleaf-extras-shiro -->
<dependency>
<groupId>com.github.theborakompanioni</groupId>
<artifactId>thymeleaf-extras-shiro</artifactId>
<version>2.0.0</version>
</dependency>
②ShiroConfig中添加配置
//整合ShiroDialect:用来整合Shiro thymeleaf
@Bean
public ShiroDialect getShiroDialect(){
return new ShiroDialect();
}
③修改首页index.html
<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org"
xmlns:shiro="http://www.thymeleaf.org/thymeleaf-extras-shiro">
<head>
<meta charset="UTF-8">
